    PR10854 cont'd: Add a testcase for the reproducer

commit a1995fef7f86ee6d1c3860cfb7e2652d986e4aa9
Author: Josh Stone <jistone@redhat.com>
Date:   Tue Oct 27 12:15:29 2009 -0700

    PR10854: Use a mutex around transport startup/shutdown
    
    We had a race where the probe setup could be called during/after the
    probe shutdown in abnormal circumstances, which leads to kernel
    callbacks still registered after module unload.  (BOOM)
    
    Now the setup/shutdown activities and related flags are guarded by a
    mutex, so we should have strict ordering.
    
    * runtime/transport/transport.c (_stp_transport_mutex): New.
      (_stp_handle_start): Grab the mutex, and make sure we're not exiting.
      (_stp_cleanup_and_exit): Grab the mutex.
      (_stp_lock_inode, _stp_unlock_inode): Use kernel version for checking
      inode locking type.
